The removal of the backdoor-generation function and the compromised code from SolarWinds binaries in June could indicate that, by this time, the attackers had reached a sufficient number of interesting targets, and their objective shifted from deployment and activation of the backdoor (Stage 1) to being operational on selected victim networks, continuing the attack with hands-on-keyboard activity using the Cobalt Strike implants (Stage 2).
Sleep Attack Activation Code [crack]
The attackers achieved this by having the SolarWinds process create an Image File Execution Options (IFEO) Debugger registry value for the process dllhost.exe (step #3). This is a known MITRE ATT&CK technique used for persistence, but it could also be abused to trigger execution of malicious code when a certain process is launched. Once the registry value is created, the attackers simply wait for the occasional execution of dllhost.exe, which might happen naturally on a system. This execution triggers a process launch of wscript.exe configured to run the VBScript file dropped in step #4.
Aircrack-ng can recover the WEP key once enough encrypted packets have been captured with airodump-ng. This part of the aircrack-ng suite determines the WEP key using two fundamental methods. The first method is via the PTW approach (Pyshkin, Tews, Weinmann). The default cracking method is PTW. This is done in two phases. In the first phase, aircrack-ng only uses ARP packets. If the key is not found, then it uses all the packets in the capture. Please remember that not all packets can be used for the PTW method. This Tutorial: Packets Supported for the PTW Attack page provides details. An important limitation is that the PTW attack currently can only crack 40 and 104 bit WEP keys. The main advantage of the PTW approach is that very few data packets are required to crack the WEP key.
By using a series of statistical tests called the FMS and Korek attacks, votes are accumulated for likely keys for each key byte of the secret WEP key. Different attacks have a different number of votes associated with them since the probability of each attack yielding the right answer varies mathematically. The more votes a particular potential key value accumulates, the more likely it is to be correct. For each key byte, the screen shows the likely secret key and the number of votes it has accumulated so far. Needless to say, the secret key with the largest number of votes is most likely correct but is not guaranteed. Aircrack-ng will subsequently test the key to confirm it.
The techniques and the approach above do not work for WPA/WPA2 pre-shared keys. The only way to crack these pre-shared keys is via a dictionary attack. This capability is also included in aircrack-ng.
Best practice recommends dismounting any encrypted, non-system disks when not in use, since most disk encryption softwares are designed to securely erase keys cached in memory after use.[21] This reduces the risk of an attacker being able to salvage encryption keys from memory by executing a cold boot attack. To minimize access to encrypted information on the operating system hard disk, the machine should be completely shut down when not in use to reduce the likelihood of a successful cold boot attack.[2][22] However, data may remain readable from tens of seconds to several minutes depending upon the physical RAM device in the machine, potentially allowing some data to be retrieved from memory by an attacker. Configuring an operating system to shut down or hibernate when unused, instead of using sleep mode, can help mitigate the risk of a successful cold boot attack.
A vulnerability in the MySQL Server database could allow a remote, authenticateduser to inject SQL code that runs with high privileges on a remote MySQL Serverdatabase. A successful attack could allow any data in the remote MySQL databaseto be read or modified. The vulnerability occurs due to insufficient validationof user-supplied data as it is replicated to remote MySQL Server instances.
A typical attack starts by the attacker tricking the victim into visiting a website containing malicious code that then runs on the victim's web browser. SameOrigin Policy (SOP) restrictions in web browsers prevent this code from directlyaccessing the cookie the attacker is trying to steal, but HTTP requests that thecode sends to the web server automatically have the cookie added, and thisbehavior is used in the attack.
The malicious code sends an HTTP request that guesses the value of the firstbyte of the cookie and positions this byte in a specific location. The attackermodifies the encrypted HTTP request such that this byte is used as a paddingvalue. If the server accepts the modified request, the value guessed wascorrect; if not, the code guesses a different value in a new request. Thisprocess is repeated until the entire cookie is disclosed.
A remote user can create a specially crafted iWork file that, when loaded by thetarget user, will trigger a memory corruption error and execute arbitrary code.The attacker must deliver and then convince the local user to open the maliciousiWork file.
GNU Bash through 4.3 processes trailing strings after function definitions inthe values of environment variables, which allows remote attackers to executearbitrary code via a crafted environment, as demonstrated by vectors involvingthe ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules inthe Apache HTTP Server, scripts executed by unspecified DHCP clients, and othersituations in which setting the environment occurs across a privilege boundaryfrom Bash execution, a.k.a. "Shellshock."
Sophos Disk Encryption (SDE) 5.x in Sophos Enterprise Console (SEC) 5.x before5.2.2 does not enforce intended authentication requirements for a resume actionfrom sleep mode, which allows physically proximate attackers to obtain desktopaccess by leveraging the absence of a login screen.
Adobe Acrobat and Reader version 9.0 and earlier are vulnerable to a bufferoverflow, caused by improper bounds checking when parsing a malformed JBIG2image stream embedded within a PDF document. By persuading a victim to open amalicious PDF file, a remote attacker could overflow a buffer and executearbitrary code on the system with the privileges of the victim or cause theapplication to crash.
The vulnerability is exploited by convincing a victim to open a maliciousdocument on a system that uses a vulnerable version of Adobe Acrobat or Reader.An attacker must deliver a malicious document to the victim and relies upon theuser to open it. Then the code execution achieved by the attacker depends on theprivilege level of the user on the system and could potentially result in Highimpacts to Confidentiality, Integrity, and Availability.
The Bluetooth Stack 2.1 in Microsoft Windows Vista SP1 and SP2 and Windows 7Gold and SP1 does not prevent access to objects in memory that (1) were notproperly initialized or (2) have been deleted, which allows remote attackers toexecute arbitrary code via crafted Bluetooth packets, aka "Bluetooth StackVulnerability."
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does notproperly restrict processing of ChangeCipherSpec messages during the SSL/TLShandshake. A ChangeCipherSpec message tells the client/server to switch fromunencrypted to encrypted communication. If a ChangeCipherSpec message is sent bythe attacker after the connection is initiated but before the master secret hasbeen generated, OpenSSL will generate the keys for the handshake with an emptymaster secret. This zero-length master key allows an attacker to crack theencryption and consequently obtain sensitive information and/or modify SSL/TLStraffic. Note that an attacker requires a man-in-the-middle position with theclient user in order to exploit this attack.
This vulnerability allows remote attackers to execute arbitrary code onvulnerable installations of Google Chrome. User interaction is required toexploit this vulnerability in that the victim must visit a malicious page oropen a malicious file.
The specific flaw exists within the handling of JPEG 2000 images. A speciallycrafted JPEG 2000 image embedded inside a PDF can force Google Chrome to writememory past the end of an allocated object. An attacker can leverage thisvulnerability to execute arbitrary code under the context of the currentprocess.
An attacker creates a PDF file embedding a maliciously crafted JPEG 2000 image.This is made available to victims, e.g., via a web page. A victim opens the PDFdocument using a Google Chrome browser, and the browser displays the PDF usingthe built-in PDFium PDF viewer. This triggers the exploit and runs theexecutable code that the attacker placed in the image, taking over the browser.
The attacker creates a link to a WordPress website running a vulnerable versionof the WP Mail plugin. This link contains malicious JavaScript code for thereplyto parameter. The attacker fools a victim into visiting the link, e.g.,by sending the link to the victim in an email or posting the link on a websiteand hoping it will be clicked.
A remote code execution vulnerability exists in the way the scripting enginehandles objects in memory in Microsoft browsers. The vulnerability could corruptmemory in such a way that an attacker could execute arbitrary code in thecontext of the current user. An attacker who successfully exploited thevulnerability could gain the same user rights as the current user. If thecurrent user is logged on with administrative user rights, an attacker whosuccessfully exploited the vulnerability could take control of an affectedsystem. An attacker could then install programs; view, change, or delete data;or create new accounts with full user rights.
After cutscenes, the next part of the story gives you a bit of mystery to solve. There's a code you need to crack, but your allies provide little help beyond "search the town," and even the Pink Dot of Plot decides to take a holiday.
As mentioned above, the Hacktool:Win32/Keygen tool allows users to "crack" (illegally register) various software. It simply forges activation keys/license files to trick programs into believing that they are activated. This tool itself is not harmful (other than it diminishes the revenue of software developers), but is often distributed together with viruses. 2ff7e9595c
